AASS Wastewater Treatment Plant

Entre Rios, Ecuador

The walls of this plant were cast using the Machihembrado method. Because of this approach, Xypex Dry-Pac and Xypex Patch'n Plug were required to seal the construction joints. The same Xypex treatment was used on 518 m of cold joints and cracks. After these structural defects were repaired, the surfaces were treated with a two-coat application of Xypex Concentrate.

American Furniture Manholes

Texas, USA

A new American Furniture and Mattress
warehouse was built in Webster, Texas, requiring
the installation of sanitary and storm
water manholes and a catch basin.

The design team was looking for corrosion
protection for the manholes and chose Xypex
Bio-San C500 over the alternate antimicrobial
admixture. Xypex Bio-San C500 was
chosen because it provides the precast sewage
elements with protection against microbial
induced corrosion and aggressive chemicals,
as well as waterproofing and crack
healing properties. The precast manufacturer
reported that there were no operational or
fabrication issues associated with including
Xypex Bio-San C500 in the wet cast mix.

Bahr Dar Air Force Camp

Bahr Dar, Ethiopia

A two-coat application of Xypex Concentrate and Modified was used to repair and waterproof the interior surface of the swimming pool, water reservoirs, and six chamber septic tanks. Patch'n Plug was used to repair the poor quality concrete that was full of voids and honeycombing. A total of 3,940 kg of Xypex Concentrate, 2,350 kg of Xypex Modified and 1,330 kg of Xypex Patch'n Plug was utilized.

Bailonggang Wastewater Treatment Plant

Shanghai, China

All internal concrete faces of the eight digesters were treated with Xypex Concentrate. In areas where anaerobic activity and a highly aggressive chemical environment were anticipated, an acid-resistant lining was applied. However, the designers specified that Xypex also be applied to these specific areas as well, not only to provide secondary protection for the concrete but also to enhance the performance and durability of the primary acid-resistant lining.

Blue Plains Wastewater Treatment Plant

Washington, DC, USA

The slurry wall sections are over 30 ft. deep and 18-in. wide. The concrete, designed to be flowable, incorporates pea gravel as the aggregate. The wall forms were filled with water at the time of the pours and then the water was displaced as the concrete filled the cavity. The project used Admix C-500 in soluble bags for just over 15,000 cubic yards of concrete.

The completed system addition, to be operational in 2015, brings a 1930’s facility into the 21st century.

Bogotá Wastewater Treatment Plant

Bogotá, Colombia

This is the first of three Bogotá wastewater treatment plants to be treated with Xypex products. Xypex Patch'n Plug was used to repair defects and stop water leakage in the concrete before application of the coating system. More than 5,000 kg of Xypex products was used in the concrete waterproofing process.

Boston CSO Project

Boston, Massachusetts, USA

Prior to project start-up, CSI installed mechanical mix equipment that allows the concrete mix crews to monitor and quality check the quantity of Xypex Admix added to each pre-cast box. As the concrete cures, Xypex permanently seals the box to prevent the flow of liquids from the outside in, and the inside out. Time of manufacturing to shipping was cut from 30 days to less than 10.
